JOHN HARVEYDE BOE,

i RIM Application r'i1ed November tion.

My "invention relates to automobile rims and has particular reference to means for locking the sections of a circumferentially divided rim. The primary object of the invention is to provide an efficient locking means which will absolutely hold the rim sections in locked relation and which is readily applied and easily manipulated.

A further object of the invention is' to.

provide a rim-lock constructed in a novel form and designed to operate in a new and eflicient manner.

lith these and such other objects in view as will be apparent from the description, my invention resides in the novel construction, combination and arrangement of parts hereinafter described and claimed and illustrated in the accompanying drawings, in which-n Figure 1 is an inner plan view of a portion of a rim showing my lock as applied with the rim sections in locked position;

Fig. 2, a similar view with the lock member disengaged;

Fig. 3; a sectional view on the line 33 of Figure 2;

Fig. 4, a perspective of the lock plate employed; and

Fig. 5, a perspective illustrating the pin by which the locking plate is attached.

My improved lockis adapted to be used in connection with circumferentially divided rims7 and comprises a plurality o f the lock ing means shown, the details of only one being illustrated. As illustrated in Figure 1; the rim consists of the two sections 1 vand 2; one section of which carries positioning lugs 3 adapted to be received in suitable recesses formed in the other of said sections, whereby to prevent longitudinal slipping of the sections relative to one another. Each of said sections is formed on its innerl surface with the projecting lug 5, the lugs being disposed in alignment transversely of the rim; for a purpose to be described.

One of said rim sections is provided with a pin @adapted to be threaded into the section and projecting from the inner surface l risata PATENT forgFic-E.

thereof, .and providedV with an enlarged head Z havin-g afreduced portion 8 adapted'tobe disposed in a slot 9 formed in a locking plate 1() carried by the pin an-d held against the inner surface of the rim sections by means of the enlarged head 7, as illustrated in Figures 1 and 2. The locking plate 10 comprises a substantially rectangular member having a recess 11 formed in one edge thereof whereby to provide shoulders 12 at the recess 11 is such as to receive the lugs 5 carried by the rim sections an-d the length of the recess is such as to provide for an engagement of the shoulders 12 around the opposite ends of the plate. The depth ofl lugs 5 when the rim sections are in connecte ed position, as illustrated in Figure 1. The vopposite edge of the plate `10 is provided with a substantial arcuate recess 13;.which is adapted to receive one end of a latch mem-v ber 14 pivoted on one of the sections at a point spaced laterally from the locking plate. In operation, the rim sections 1 and 2 are joined and the locking plate 10, by reasonr of the disposition of pin 6, and elongated slot 9, is then slipped into engagement with' the lugs 5 to retain the same within the` recess 11 against the shoulders 12; and the latch member 14 is then swung into engagement with the recess 13; whereby said locking plate will be eifectually held in position and the rim sections will be prevented from becoming detached owing to the engagement of the lugs and shoulders as described. To

unfasten4 the parts, it is siinply necessary to. release the latch member 14 whereupon the locking plate 1() may be slipped to disengage the shoulders 12 from thev rim lugs whereupon the parts may be disassembled.

While I have shown and described certain details and materials which enter into the construction and operation of my invention;

'I desire it to be understood that l1 do not. intend to limit myself to these, but that any suchmay be used as will fall within the scopeof the invention as claimed.

I claim:

1. ln a circumferentially divided mountable rim; a plurality of lugs carried by the iim sections; headed pins carried by one of said sections;` locking plates secured to said section by means of said pins, said plates being provided with elongated apertures to receive said pins for slidable movement of the plates relative to the rim section, shoulders formed on said plates for endei gagement with said rim lugs to retain the rim sevtions in joined position, and lateh men'ibers carried by one of said rim sections and adapted to engage said looking plates to hold same in locked position. l

2. ln a den'iountalole rim havingl oiroumn ferentially divided rim sections7 a plurality of substantially rectangular looking plates provided at substantially their central portions With elongated apertures7 headed pins disposed in said apertures and adapted to be engaged'in a rim section for disposing` said loeling` members in slidable relation thereon7 shoulders carried byi said locking plates, means on the rim seetions adapted .or engagement with said shoulders for locking JOHN HARVEY DE Bon.
